Waters, who was once viewed as a lock for the first day before tearing his ACL in the first game of his senior season, is quickly rising back up draft boards after running 4.62 in the 40-yard dash Tuesday during a workout for 18 scouts at Clemson.
The time was a tenth of a second faster than his previous best before his injury.
Waters will also meet with the Chargers, Rams and Jets before the draft.
In college, Waters was a productive defender who was utilized mostly as a middle linebacker. In the NFL, he could play the same position either in a 3-4 or 4-3 scheme but some scouts have already red-flagged him because of the knee injury he suffered last September.
However, those same scouts cannot question his size (6-3, 240) and speed. In addition, Waters was thought of as a true "team player" at Clemson. After tearing his ACL during the Tigers' 2006 season opener against Florida Atlantic, Waters continued to travel with the team and attend practice sessions.
He was also instrumental in the development of Clemson's younger linebackers.
"I always had the younger linebackers coming up to me each day asking what they should be working on and they should be working on and what they should be looking for during the games," Waters told Scout.com at the NFL Combine in February.
Scout.com currently lists Waters as the No. 4 overall middle linebacker prospect available in the 2007 NFL Draft.
"Hopefully I'll go on the first day, but if not it's already been proven that the first day guys aren't necessarily the best guys," he said. "It's just a great opportunity for me."
